Wiring
The preferred method of bringing input signal in to the amplifier is with RCA
cables from a quality tape or CD player. A high (speaker) level input signal may also
be used if your factory deck or aftermarket source does not have low level RCA
jacks. It is not recommended to mix high and low level inputs. Engine noise in the
system will probably result.
Some of the system possibilities are shown in the System Diagrams section of
this manual.
When working with power connections always hook up the ground wire first
and disconnect the ground wire last. Never make any wiring changes with the
amplifier powered up.
The chassis mounted fuse(s) are in place to protect the circuitry of the
amplifier in the event of major trouble. An in-line fuse must be installed within 18
inches of the battery to protect the power wire used to supply current to the
amplifier. For the Kicker Impulse IX405D amplifier a fuse value of 60A and 8 gauge
power wire are recommended. If the power wire is longer than 10 feet, we rec-
ommend that the wire size be 4 gauge to reduce losses.
Any time that a power wire goes through a metal panel such as the firewall,
or if there is any chance of abrasion, it is necessary to use a grommet or other
suitable form of protection to avoid shorts.
The ground wire should be at least 8 gauge, as short as possible and
attached to the body of the vehicle. The ground point must be free from paint
and corrosion. We recommend using the same gauge wire for power and ground.
Mounting the IMPULSE Amplifier
After determining an appropriate mount-
ing location which provides good air circulation
and access to the end panel controls, use the
supplied screws and washers to firmly mount
the amplifier. The amplifier chassis can be
used as a template for the screw locations.
Check to make sure that the mounting screws
will not damage any components on the back
side of the chosen mounting surface.
If a vertical mounting surface is chosen,
we recommend that the heatsink fins run ver-
tically as shown for improved cooling.
The subwoofer remote controller can be
mounted in any convenient location in the
vehicle. It should be within easy reach of the
driver to avoid any dangerous situations while
driving.
